A year ago, Fox popped the question to Heather Terwilliger while at a New York Yankees game but dropped the ring. Even worse, the proposal was shown on the stadium's Jumbotron.

Strangers in their section scrambled to search for the ring while sportscasters watched in horror.

"Oh look at this poor guy," Yankees broadcaster Michael Kay said.

Terwilliger eventually realized that the ring had landed in the cuff of her jeans.

But the high-profile fail made them overnight viral sensations. It even led to an appearance on The Ellen DeGeneres Show, where the couple was awarded $10,000 from Shutterfly for their "memorable moment."

But just a year on, the couple has broken up.

"Turns out she was a completely different person than who I thought she was," Fox told Inside Edition.

Terwilliger said: "I think he was more interested in the attention than anything else."

She said the problems started after their appearance on Ellen when she says Fox took off with the $10,000.

"I checked the bank balance and it said zero," she said.

Fox claims he offered the money back to the Ellen show but never heard from them.
